^I thought they seemed tired too but the intro to RDR was perfect imo and they still nailed the choreography for both songs but in Hoot you could hear how tired they sounded. idk who it was, but someone had their mic too loud or something and you could hear how they were half singing the song and half breathing heavily in the chorus lol (sounds like me when I workout to snsd and try to sing along
)
edit: I think it's Yuri lol. when her "nun nun nun" part comes on her voice sounds almost the same as that breathing-heavy voice in the chorus. damn she sounded bad. :/ but REALLY bad sound system.
